Hello! I know very little about pickups and stuff, but I had a question... How do I get the effect he gets at 2:20 in this video.

I have this same guitar with 2 pickups... I want to record like this... Would a 2 channel USB interface work to record like this?
Like the Focusrite Scarlett 2i2.
Would this one work? Is this, indeed, 2 channels? Do I need 2 channels to do this...?

Forgive my ignorance, I have never played with electric acoustics before I bought this guitar just the other day.

But, it is a super cool effect and would love to use it in recording some of my music!

A 2 channel interface like that would indeed suffice for this if you want to have two individual tracks from each pickup. If I understand what he was saying right, you can get the same effect by blending on the guitar with a single output.

All he did was pan out each pick up hard left and right which widens the stereo image.

What you'll do is create two audio tracks in your recording software(some software can have a stereo track, but it's easier to do separate two mono tracks), then you'll set the input of the first track to be input 1, and the second track to be input 2.

Then once you've recorded the two mono tracks, you grab the pan knob on each track in the software, and turn it as far left or right as you'd like to get that stereo separation.

Personally, I don't pan hard, I usually only pan part of the way in each direction so there's some common ground in the center of the song. Of course that's all up to your taste, try everything and see what your ears like best!
